\noindent{\it Last Revised: December 1, 2015}\\
\noindent{\bf Filename: warmboot} \\


\noindent {\bf BRIEF FUNCTIONAL DESCRIPTION:} \\
\normalsize
This is an ``atomic'' procedure which warm boots the active ACIS BEP.
ACIS flight software can be booted in either cold or warm.  
The warm boot reloads the flight code, applies patches and bad 
pixel/column lists, and cleans up memory buffers.

\vspace{0.25in}
\noindent The sequence of actions will be: 
\be
\item set the boot-from-uplink flag to zero (should already be zero)
\vspace{-0.10in}
\item set the warm boot flag on
\vspace{-0.10in}
\item halt the active BEP
\vspace{-0.10in}
\item restart the active BEP
\vspace{-0.10in}
\item verify BEP booted from SW TLM verifiers
\vspace{-0.10in}
\item check HW LEDs
\vspace{-0.10in}
\item check SW LEDs

\noindent {\bf OPERATIONAL CONSTRAINTS/CAUTIONS:} \\
\normalsize
This procedure does not change the active BEP, whichever BEP is
selected get warmbooted.\\
This procedure resets the threshold crossings patch parameters.

\normalsize

{\bf V1.2}
\begin{itemize}
\item changed Time Req for all steps
\item removed reference to a specific version number of the flight SW
\item added to check that the warmbootFlag = 1
\item added steps 1.5, 1.6, and 1.7 to verify the BEP boot
\end{itemize}

{\bf V2.0}
\begin{itemize}
\item ACIS Team signed-off version
\item changed expected value of SW version number to ?? in step 1.5
\item changed expected value of warmbootFlag to 1 in step 1.5
\item changed expected value of ``1STAT7ST'' in step 1.6
\end{itemize}

{\bf V2.1}
\begin{itemize}
\item Added warning about txings parameter reset\\
\end{itemize}
